BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to benzene, pyridine, and pyridazine derivatives and more specifically to such compounds that are useful in the treatment and/or prevention of diseases and/or conditions related to cell proliferation, such as cancer, inflammation and inflammation-associated disorders, and conditions associated with angiogenesis. Compounds of the invention are also useful in the treatment and/or prevention of infectious diseases, in particular, fungal infections.

2. Description of the Related Art

Cancer is characterized by abnormal cellular proliferation. Cancer cells exhibit a number of properties that make them dangerous to the host, typically including an ability to invade other tissues and to induce capillary ingrowth, which assures that the proliferating cancer cells have an adequate supply of blood. A hallmark of cancerous cells is their abnormal response to control mechanisms that regulate cell division in normal cells and continue to divide until they ultimately kill the host.

Angiogenesis is a highly regulated process under normal conditions, however many diseases are driven by persistent unregulated angiogenesis. Unregulated angiogenesis may either cause a particular disease directly or exacerbate an existing pathological condition. For example, ocular neovascularization has not only been implicated as the most common cause of blindness, but also is believed the dominant cause of many eye diseases. Further, in certain existing conditions, for example arthritis, newly formed capillary blood vessels invade the joints and destroy cartilage, or in the case of diabetes, new capillaries formed in the retina invade the vitreous, bleed, and cause blindness. Growth and metastasis of solid tumors are also dependent on angiogenesis (Folkman, J., Cancer Research, 46, 467-473 (1986), Folkman, J., Journal of the National Cancer Institute, 82, 4-6 (1989). It has been shown, for example, that tumors which enlarge to greater than 2 mm must obtain their own blood supply and do so by inducing the growth of new capillary blood vessels. Once these new blood vessels become embedded in the tumor, they provide a means for tumor cells to enter the circulation and metastasize to distant sites such as liver, lung or bone (Weidner, N., et al., The New England Journal of Medicine, 324(1), 1-8 (1991). Under conditions of unregulated angiogenesis, therapeutic methods designed to control, repress, and/or inhibit angiogenesis could lead to the abrogation or mitigation of these conditions and diseases.

Inflammation is related to a variety of disorders such as pain, headaches, fever, arthritis, asthma, bronchitis, menstrual cramps, tendonitis, bursitis, psoriasis, eczema, burns, dermatitis, inflammatory bowel syndrome, Crohn's disease, gastritis, irritable bowel syndrome, ulcerative colitis, vascular diseases, Hodgkin's disease, sclerodoma, rheumatic fever, type I diabetes, myasthenia gravis, sarcoidosis, nephrotic syndrome, Behcet's syndrome, polymyositis, hypersensitivity, conjunctivitis, gingivitis, post-injury swelling, myocardial ischemia, and the like.

Heat-shock protein 90 (HSP-90) is a cellular chaperone protein required for the activation of several eukaryotic protein kinases, including the cyclin-dependent kinase CDK4. Geldanamycin, an inhibitor of the protein-refolding activity of HSP-90, has been shown to have antiproliferative and antitumor activities.

HSP-90 is a molecular chaperone that guides the normal folding, intracellular disposition and proteolytic turnover of many key regulators of cell growth and survival. Its function is subverted during oncogenesis to make malignant transformation possible and to facilitate rapid somatic evolution, and to allow mutant proteins to retain or even gain function. Inhibition of HSP-90 will slow those process thus has potential therapeutic use (Whitesell L, Lindquist, S L, Nature Rev. Cancer, 2005, 10, 761-72).

Ansamycin antibiotics, e.g., herbimycin A (HA), geldanamycin (GM), and 17-allylaminogeldanamycin (17-AAG) are thought to exert their anticancerous effects by tight binding of the N-terminus pocket of HSP-90, thereby destabilizing substrates that normally interact with HSP-90 (Stebbins, C. et al. Cell 1997, 89, 239-250). This pocket is highly conserved and has weak homology to the ATP-binding site of DNA gyrase (Stebbins, C. et al., supra; Grenert, J. P. et al. J. Biol. Chem. 1997, 272, 23843-50).

In vitro and in vivo studies have demonstrated that occupancy of this N-terminal pocket by ansamycins and other HSP-90 inhibitors alters HSP-90 function and inhibits protein folding. At high concentrations, ansamycins and other HSP-90 inhibitors have been shown to prevent binding of protein substrates to HSP-90 (Scheibel, T. H. et al. Proc. Natl. Acad. Sci. USA 1999, 96, 1297-302; Schulte, T. W. et al. J. Biol. Chem. 1995, 270, 24585-8; Whitesell, L., et al. Proc. Natl. Acad. Sci. USA 1994, 91, 8324-8328). Ansamycins have also been demonstrated to inhibit the ATP-dependent release of chaperone-associated protein substrates (Schneider, C. L. et al. Proc. Natl. Acad. Sci., USA 1996, 93, 14536-41; Sepp-Lorenzino et al. J. Biol. Chem. 1995, 270, 16580-16587). In either event, the substrates are degraded by a ubiquitin-dependent process in the proteasome (Schneider, C. L., supra; Sepp-Lorenzino, L., et al. J. Biol. Claim. 1995, 270, 16580-16587; Whitesell, L. et al. Proc. Natl. Acad. Sci. USA 1994, 91, 8324-8328). HSP-90 substrate destabilization occurs in tumor and non-transformed cells alike and has been shown to be especially effective on a subset of signaling regulators, e.g., Raf (Schulte, T. W. et al., Biochem. Biophys. Res. Commun. 1997, 239, 655-9 Schulte, T. W., et al., J. Biol. Chem. 1995, 270, 24585-8), nuclear steroid receptors (Segnitz, B.; U. Gehring J. Biol. Chem. 1997, 272, 18694-18701; Smith, D. F. et al. Mol. Cell. Biol. 1995, 15, 6804-12), v-Src (Whitesell, L. et al. Proc. Natl. Acad. Sci. USA 1994, 91, 8324-8328) and certain transmembrane tyrosine kinases (Sepp-Lorenzino, L. et al. J. Biol. Chez. 1995, 270, 16580-16587) such as EGF receptor (EGFR) and HER2/Neu (Hartmann, F., et al. Int. J. Cancer 1997, 70, 221-9; Miller, P. et al. Cancer Res. 1994, 54, 2724-2730; Mimnaugh, E. G., et al. J. Biol. Chem. 1996, 271, 22796-801; Schnur, R. et al. J. Med. Chenu. 1995, 38, 3806-3812), CDK4, and mutant p53. Erlichman et al. Proc. AACR 2001, 42, abstract 4474. The ansamycin-induced loss of these proteins leads to the selective disruption of certain regulatory pathways and results in growth arrest at specific phases of the cell cycle (Muise-Heimericks, R. C. et al. J. Biol. Chez. 1998, 273, 29864-72), and apoptosis, and/or differentiation of cells so treated (Vasilevskaya, A. et al. Cancer Res., 1999, 59, 3935-40). Inhibitors of HSP-90 thus hold great promise for the treatment and/or prevention of many types of cancers and proliferative disorders, and also hold promise as traditional antibiotics.

Inhibition of HSP-90 is also known to result in up regulation of the expression of the chaperone HSP70. HSP70 up regulation is considered to be of therapeutic benefit for treatment of a wide range of neurodegenerative diseases including, but not limited to: Alzheimer's disease; Parkinson's disease; Dementia with Lewy bodies; Amyotropic lateral sclerosis (ALS); Polyglutamine disease; Huntington's disease; Spinal and bulbar muscular atrophy (SBMA); and Spinocerebellar ataxias (SCA1-3,7). Therefore, the compounds described in the invention are of potential therapeutic use for treatment of such neurodegenerative diseases (Muchowski, P. J., Wacker J. L., Nat. Rev. Neurosci. 2005, 6, 11-22.; Shen H. Y., et al. J. Biol. Chem. 2005, 280, 39962-9).

Inhibition of HSP-90 also has anti-fungal activity, both as a stand alone therapy and in combination with standard anti-fungal therapies such as the azole class of drugs. Therefore, the compounds described in the invention are of potential therapeutic use for treatment of fungal infections including, but not limited to, life threatening systemic fungal infections (Cowen, L. E., Lindquist, S., Science 2005, 309, 2185-9).

Inhibition of HSP-90 also has antimalarial activity; thus, inhibitors of this protein are useful as antimalarial drugs.

Therefore, there is a continuing need in the art for new methods of treating cancer, inflammation and inflammation-associated disorders, and conditions or diseases related to uncontrolled angiogenesis.

DETAILED DESCRIPTION OF THE INVENTION

In Formula I, R₃ and R₄ are, as noted above, independently (a) hydrogen, (b) halo, or (c) an alkyl group having from 1-15 carbon atoms. All, but no more than about six, of the carbon atoms in the alkyl group may be replaced independently by the various groups listed above in connection with Formula I.

Thus, when the alkyl group is methyl, i.e., a one carbon atom alkyl group, replacement of that carbon atom with, for example, nitrogen or sulfur, the resulting group will not be an alkyl group but instead will be an amino or thio group, respectively. Similarly, when the carbon atom being replaced terminates the alkyl group, the terminal group will become another moiety such as pyrimidinyl, amino, phenyl, or hydroxy.

Replacement of a carbon atom with a group such as, for example, oxygen, nitrogen, or sulfur will require appropriate adjustment of the number of hydrogens or other atoms required to satisfy the replacing atom's valency.

The compounds of this invention may contain one or more asymmetric carbon atoms, so that the compounds can exist in different stereoisomeric forms. These compounds can be, for example, racemates, chiral non-racemic or diastereomers. In these situations, the single enantiomers, i.e., optically active forms, can be obtained by asymmetric synthesis or by resolution of the racemates. Resolution of the racemates can be accomplished, for example, by conventional methods such as crystallization in the presence of a resolving agent; chromatography, using, for example a chiral HPLC column; or derivatizing the racemic mixture with a resolving reagent to generate diastereomers, separating the diastereomers via chromatography, and removing the resolving agent to generate the original compound in enantiomerically enriched form. Any of the above procedures can be repeated to increase the enantiomeric purity of a compound.

When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless otherwise specified, it is intended that the compounds include the cis, trans, Z- and E-configurations. Likewise, all tautomeric forms are also intended to be included.

Pharmaceutical Compositions

The compounds of general Formula I may be administered orally, topically, parenterally, by inhalation or spray or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used herein includes percutaneous, subcutaneous, intravascular (e.g., intravenous), intramuscular, or intrathecal injection or infusion techniques and the like. In addition, there is provided a pharmaceutical formulation comprising a compound of general Formula I and a pharmaceutically acceptable carrier. One or more compounds of general Formula I may be present in association with one or more non-toxic pharmaceutically acceptable carriers and/or diluents and/or adjuvants, and if desired other active ingredients. The pharmaceutical compositions containing compounds of general Formula I may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsion, hard or soft capsules, or syrups or elixirs.

Compositions intended for oral use may be prepared according to any method known in the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preservative agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients that are suitable for the manufacture of tablets. These excipients may be for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, corn starch, or alginic acid; binding agents, for example starch, gelatin or acacia, and lubricating agents, for example magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques. In some cases such coatings may be prepared by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monosterate or glyceryl distearate may be employed.

Formulations for oral use may also be presented as hard gelatin capsules, wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin or olive oil.

Formulations for oral use may also be presented as lozenges.

Aqueous suspensions contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydropropyl-methylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide, for example, lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethyleneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.

Oily suspensions may be formulated by suspending the active ingredients in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents and flavoring agents may be added to provide palatable oral preparations. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid.

Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents or suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present.

Pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil or a mineral oil or mixtures of these. Suitable emulsifying agents may be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol, anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavoring agents.

Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol, glucose or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents. The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents that have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parentally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

The compounds of general Formula I may also be administered in the form of suppositories, e.g., for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient that is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols.

Compounds of general Formula I may be administered parenterally in a sterile medium. The drug, depending on the vehicle and concentration used, can either be suspended or dissolved in the vehicle. Advantageously, adjuvants such as local anesthetics, preservatives and buffering agents can be dissolved in the vehicle.

For disorders of the eye or other external tissues, e.g., mouth and skin, the formulations are preferably applied as a topical gel, spray, ointment or cream, or as a suppository, containing the active ingredients in a total amount of, for example, 0.075 to 30% w/w, preferably 0.2 to 20% w/w and most preferably 0.4 to 15% w/w. When formulated in an ointment, the active ingredients may be employed with either paraffinic or a water-miscible ointment base.

Alternatively, the active ingredients may be formulated in a cream with an oil-in-water cream base. If desired, the aqueous phase of the cream base may include, for example at least 30% w/w of a polyhydric alcohol such as propylene glycol, butane-1,3-diol, mannitol, sorbitol, glycerol, polyethylene glycol and mixtures thereof. The topical formulation may desirably include a compound which enhances absorption or penetration of the active ingredient through the skin or other affected areas. Examples of such dermal penetration enhancers include dimethylsulfoxide and related analogs. The compounds of this invention can also be administered by a transdermal device. Preferably topical administration will be accomplished using a patch either of the reservoir and porous membrane type or of a solid matrix variety. In either case, the active agent is delivered continuously from the reservoir or microcapsules through a membrane into the active agent permeable adhesive, which is in contact with the skin or mucosa of the recipient. If the active agent is absorbed through the skin, a controlled and predetermined flow of the active agent is administered to the recipient. In the case of microcapsules, the encapsulating agent may also function as the membrane. The transdermal patch may include the compound in a suitable solvent system with an adhesive system, such as an acrylic emulsion, and a polyester patch. The oily phase of the emulsions of this invention may be constituted from known ingredients in a known manner. While the phase may comprise merely an emulsifier, it may comprise a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabilizer(s) make-up the so-called emulsifying wax, and the wax together with the oil and fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the cream formulations. Emulsifiers and emulsion stabilizers suitable for use in the formulation of the present invention include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate, and sodium lauryl sulfate, among others. The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties, since the solubility of the active compound in most oils likely to be used in pharmaceutical emulsion formulations is very low. Thus, the cream should preferably be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters may be used. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils can be used.

Formulations suitable for topical administration to the eye also include eye drops wherein the active ingredients are dissolved or suspended in suitable carrier, especially an aqueous solvent for the active ingredients. The antiinflammatory active ingredients are preferably present in such formulations in a concentration of 0.5 to 20%, advantageously 0.5 to 10% and particularly about 1.5% w/w. For therapeutic purposes, the active compounds of this combination invention are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered per os, the compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled-release formulation as may be provided in a dispersion of active compound in hydroxypropylmethyl cellulose. Formulations for parenteral administration may be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules having one or more of the carriers or diluents mentioned for use in the formulations for oral administration. The compounds may be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, and/or various buffers. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art.

Dosage levels of the order of from about 0.1 mg to about 140 mg per kilogram of body weight per day are useful in the treatment of the above-indicated conditions (about 0.5 mg to about 7 g per patient per day). The amount of active ingredient that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. Dosage unit forms will generally contain between from about 1 mg to about 500 mg of an active ingredient. The daily dose can be administered in one to four doses per day. In the case of skin conditions, it may be preferable to apply a topical preparation of compounds of this invention to the affected area two to four times a day.

It will be understood, however, that the specific dose level for any particular patient will depend upon a variety of factors including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, route of administration, and rate of excretion, drug combination and the severity of the particular disease undergoing therapy.

For administration to non-human animals, the composition may also be added to the animal feed or drinking water. It may be convenient to formulate the animal feed and drinking water compositions so that the animal takes in a therapeutically appropriate quantity of the composition along with its diet. It may also be convenient to present the composition as a premix for addition to the feed or drinking water. Preferred non-human animals include domesticated animals.

The compounds of the present invention may be administered alone or in combination with at least one additional therapeutic agent or therapy, e.g., radiation therapy, to a patient in need of such treatment. The additional therapeutic agent or therapy may be administered at the same time, separately, or sequentially with respect to the administration of a compound of the invention. Such additional therapeutic agents included, but are not limited to, anti-cancer agents, anti-inflammatory agents, and the like.

2-Bromo-4-(2,6,6-trimethyl-4-oxo-4,5,6,7-tetrahydro-indol-1-yl)-benzonitrile (107.2 mg, 0.3 mmol), aniline (111.8 mg, 1.2 mmol), Pd(OAc)₂ (10.1 mmol, 5 mol %), DPPF (16.6 mg, 10 mol %), and NaOtBu (57.7 mg, 0.6 mmol) were placed in a Personal Chemistry Microwave Vial. The reagents were suspended in 2.5 mL of anhydrous toluene and the vessel purged with nitrogen. The reaction vessel was sealed and heated to 110° C. for 480 seconds. Upon cooling, the reaction mixture was filtered through SiO₂ (eluted with 2:1 EtOAc/hexanes) and the eluent concentrated in vacuo. The residue was then dissolved in 2 mL EtOH and treated with 0.6 mL of 1 N NaOH and a catalytic amount of H₂O₂. After stirring this solution at 50° C. for 2 hours, the mixture of nitrile and amide was purified by column chromatography (silica, EtOAc/hexanes). The product 2-(phenylamino)-4-(2,6,6-trimethyl-4-oxo-4,5,6,7-tetrahydroindol-1-yl)benzamide was isolated as a yellow powder (55.6 mg, 47%). (100% clean by LC/MS, product M+H=388.1). The corresponding nitrile was also isolated (46.9 mg, 42%). (100% clean by LC/MS).

Biological Evaluation Example 48 Cell Proliferation Assays

A panel of cancer cell lines was obtained from the DCTP Tumor Repository, National Cancer Institute (Frederick, Md.) or ATCC (Rockville, Md.). Cell cultures were maintained in Hyclone RPMI 1640 medium (Logan, Utah) supplemented with 10% fetal bovine serum and 20 mM HEPES buffer, final pH 7.2, at 37° C. with a 5% CO₂ atmosphere. Cultures were maintained at sub-confluent densities. Human umbilical vein endothelial cells (HUVEC) were purchased from Clonetics, a division of Cambrex (Walkersville, Md.). Cultures were established from cryopreserved stocks using Clonetics EGM-2 medium supplemented with 20 mM HEPES, final pH 7.2, at 37° C. with a 5% CO₂ atmosphere.

For proliferation assays, cells were seeded with the appropriate medium into 96 well plates at 1,000-2,500 cells per well, depending on the cell line, and were incubated overnight. The following day, test compound, DMSO solution (negative control), or Actinomycin D (positive control) was added to the appropriate wells as 10× concentrated stocks prepared in phosphate buffered saline. The cell plates were then incubated for an additional 2-5 days, depending on the cell line, to allow proliferation to occur. To measure cell density, 50 μL of WST-1 solution (Roche Applied Science, Ind.) diluted 1:5 in phosphate buffered saline was added to each well, and the cells incubated for an additional 1-5 hrs., again depending on the cell line. Optical density was determined for each well at 450 nM using a Tecan GeniosPro plate reader (RTP, NC). The percentage of cell growth was determined by comparing the cell growth in the presence of test compounds to the cells treated with DMSO vehicle (control, 100% growth) and cells treated with Actinomycin D (10 μM, 0% growth).

Immediately after the WST-1 determination, the medium was removed from the PC-3, NCI-H460 and HUVEC cell lines, and the plates stored at −80° C. Using these assay plates, relative amounts of DNA in each well were determined using the Cyquant DNA assay kit from R&D Systems (Eugene, Oreg.) following the manufacturer's directions. Results for each compound treatment were compared to DMSO vehicle control (100%) and 10 μM Actinomycin D treated cells (0%).

Several exemplary compounds useful in the methods of the invention are listed below. The range of their inhibitory activity against PC-3 cell proliferation is demonstrated, where +++ stands for an IC₅₀ value that is less than 0.5 μM, ++ between 0.5 and 5 μM, + between 5 and 50 μM.

Example 49 Determination of Affinity for HSP-90

(Heat Shock Protein 90)

Affinity of test compounds for HSP-90 was determined as follows: Protein mixtures obtained from a variety of organ tissues (for example: spleen, liver and lung) were reversibly bound to a purine affinity column to capture purine-binding proteins, especially HSP-90. The purine affinity column was washed several times, and then eluted with 20 μM, 100 μM, and 500 μM of test compound. Compounds of Formula I elute HP-90 in a dose-dependent manner vs. a control elution using dimethylsulfoxide. The elution profile of Formula I compounds was determined by 1-dimensional SDS polyacrylamide gel electrophoresis. Gels were stained with a fluorescent stain such as sypro ruby (a highly sensitive fluorescent protein stain that can readily detect less than 1 fmol of total protein, i.e., less than 0.04 ng for a 40 kDa protein) or silver nitrate. The gels were imaged using a standard flat bed gel imager and the amount of protein estimated by densitometry. The percent of HSP-90 protein eluted from the column at each concentration was determined and IC₅₀ values were calculated from these estimates. The identity of a band containing HSP-90 was determined by protein sequencing using mass spectroscopy.

Compounds of the invention are inhibitors of HSP-90 (heat shock protein 90). Several exemplary compounds useful in the methods of the invention are listed below. The range of their relative binding affinity to HSP-90 is demonstrated, where +++ stands for very high, ++ for high and + for moderate.
